/*1.定义一个汽车类（Car），属性有颜色，品牌，车牌号，价格，并实例化两个对象，给属性赋值，并输入属性值*/

package com.Oracle.oop1;

public class Car {
	String color;
	String brand;
	String number;
	int price;
}

package com.Oracle.oop1;

public class Text1 {

	public static void main(String[] args) {
		Car c1=new Car();
		c1.color="blue";
		c1.brand="Audi";
		c1.number="黑A888888";
		c1.price=88888;
		Car c2=new Car();
		c2.color="yellow";
		c2.brand="BMW";
		c2.number="黑B888888";
		c2.price=66666;
		System.out.print(c1.color+"\t");
		System.out.print(c1.brand+"\t");
		System.out.print(c1.number+"\t");
		System.out.println(c1.price+"\t");
		System.out.print(c2.color+"\t");
		System.out.print(c2.brand+"\t");
		System.out.print(c2.number+"\t");
		System.out.print(c2.price+"\t");
		
	}
}

/*2.定义一个球员类(Player)，属性有身高，体重，姓名，实例化两个球员，分别是姚明和科比；*/

package com.Oracle.oop1;

public class Player {
	int height;
	int weight;
	String name;
}

package com.Oracle.oop1;

public class Text2 {

	public static void main(String[] args) {
		Player p1=new Player();
		p1.name="姚明";
		p1.height=210;
		p1.weight=85;
		Player p2=new Player();
		p2.name="科比";
		p2.height=210;
		p2.weight=88;
		System.out.print(p1.name+"\t");
		System.out.print(p1.height+"\t");
		System.out.println(p1.weight+"\t");
		System.out.print(p2.name+"\t");
		System.out.print(p2.height+"\t");
		System.out.print(p2.weight+"\t");
	}
}

/*3.定义一个僵尸类(Zombie)，属性有名子，体力值，攻击力，实例化三个僵尸类，并给属性赋值；*/

package com.Oracle.oop1;

public class Zombie {
	String name;
	int power;
	int ATK;
	void  print() {
		System.out.print("名字："+name);
		System.out.print("\t体力值："+power);
		System.out.println("\t攻击值："+ATK);
	}

}

package com.Oracle.oop1;

public class Text3 {

	public static void main(String[] args) {
		Zombie z1=new Zombie();
		Zombie z2=new Zombie();
		Zombie z3=new Zombie();
		z1.name="铁桶僵尸";
		z1.power=200;
		z1.ATK=300;
		z2.name="孕妇僵尸";
		z2.power=300;
		z2.ATK=250;
		z3.name="超级僵尸";
		z3.power=888;
		z3.ATK=888;
		z1.print();
		z2.print();
		z3.print();
	}

}

//4.打印int，char， float，double，String ，boolean这些数据类型作为类属性时的默认值

package com.Oracle.oop1;

public class Default {
	int int1;
	char char1;
	float float1;
	double double1;
	String string1;
	boolean bool;
}

package com.Oracle.oop1;

public class Text4 {

	public static void main(String[] args) {
		Default d=new Default();
		System.out.println(d.int1);
		System.out.println(d.char1);
		System.out.println(d.float1);
		System.out.println(d.double1);
		System.out.println(d.string1);
		System.out.println(d.bool);
	}
